Brentford chief executive officer Andrew Mills is stepping down from his role after three years at Griffin Park.
The news comes on the day the Bees announced former Manchester City striker Uwe Rosler as their new manager. A backroom reshuffle will also see former first-team coach Mark Warburton become the club's sporting director.
Mills said: "As plans for the restructure take shape I feel it is right for me to step aside."
He added: "I would like to formally place on record my gratitude for the experience and support of the board during my proud time as chief executive.
"I will cherish memories of clinching the League Two title at Darlington, beating Everton at Griffin Park, taking Birmingham to penalties and the proudest moment in my career so far - representing the club at Wembley in front of 28,000 expectant Bees."
